Toal l ma concern] Be it known that-we, RICHARD .terial the variousparts of a:shoe upper.

In the ordinary practice, the pattern outlining the shoe part to be cutfrom the upper material .is-placcd on the sheet ofupper material andaknife' is drawn ,by' hand around the edgesof the pattern, cutting outthe shoe part outlined by'the pattern.- Subsequently, the cut-out part13 covered with' a stencil plateand suitable indie-ation ma-rksf pl acedthereon by punches or by .coloni'ng matter {suitably applied. In

someinstances special machines, such lmttonhole marking machines, areemployed to mark the parts. It will be evident, therefore, that twodistinct operations have heretofore been necessary to cut out and mark'the various parts of the shoe. These marks vary-in character from theshape of the buttonhole, the point of attachment of the button, toindications "for the junction of parts. I As this marking has beenaccomentirely satisfactory. \Vhen punches or prick awls have beenemployed, the material,' particularly soft leather or cloth, closes upafter the mark has heenvmade so that subsequently it is not discernible.The use of coloring matter is injurious to the leather as the liquid orpaste will spread. or smear..

is easily rubbed off inadvertently or so In the case of chalk, the vmarkblurred as to make it entirely ineffective.

Our invention provides a device which permits the cutting out of thepattern or shoe partirom the material and thesubstantiallyflsi'rnultaneous marking of the part. The marking mediumemployed is such that a dry"indelible mark is made which does I L. Lnoroand Roman D: SIMPSON, citizens of the markers.

not injure the shoe part and which is conoutline of the shoe part to becut out and provided with a series of heated cauteriz-ing 7 takes theform of a plate which may be superposed upon theshoe material withthemarkers in contactavitlrthe surface of the material, and, while acutting knife is being drawn. around its edges, the heated mark-I ersare simultaneously cautcrizing the surface of the material,providingadry; indelible mark which \vill-xiot detract from theappearance of the shoe. i

Another feature of our invention consists in a pattern platehaving-electrically heated marking meanson one face andprovided\\-'ith.electrical connections for such mark in'g means.

Another. in the hovel manner of'for'ming themark- ,iug members by theapplication of the'elec feature of the invention 'resi,des

trical-conductor to the body of the pattern.- i

plate. In the embodiment of. the ins-'en tion selected for illustration,this is accor'nplished hy lacing an. electric conducts through thepattern plate in-such a manner that marking portions of desired shapeand configuration project from one face of the plate.

Another feature of the invention consists in a structure providingdifferent patterns on opposite faces. such as patterns in reverseduplicate for right and left'hand parts, and separate electric heatingconnections for each pattern. In addition. the arrange ment ofthcelectric connections such that oniy one pattern may be heated for asingle cutting and marking operation. Means are also preferably,provided for insulating the electric circuits of the two patterns fromeach other.

A. further eat-lire consists in a pattern plate having marking portionsexposed on one face and arrangedto be electrically heated to cauterize,with electric circuit connections to said markers on theopposite face ofthe plate arranged to remain comparatively cool during the passage ofthe electric current therethrough: This feature is equally applicable tosingle and double pattern plates.

Still another feature of the invention con sists in an indicator ortell-tale positioned for observation by the operator and de signed to beheated similarly to the marking members so that the condition of theindicator is evidence of the condition of the markers.

Another and related'feature of the invention is a switch or serviceconnection for the heatin circuits, which switch includes an exposedsection of conductor similar to the heated marking portions and servingby its condition to indicate the condition of these marking portions.

Another feature resides in a service connection for the electricconductors of the heating circuit 'on the pattern plate, which makesconnection with the pattern plate at the face opposite the markingportions.

A related feature is a construction of service 'eonnection providing anoperating handle. i

From the viewpoint of opposed patterns and mai kers, a further featureof the invention resides in a service connection for use with such adevice which cooperates with the electric terminals of the heatingcircuits of the opposed patterns in such manner that only one patternmay be heated at one time.

These and other novel features'of con? struction are more fullydescribed in the following detailed specification and are illus tratedin the accompanying drawings, in which Figure l is a plan view of themarking face of the lower plate of a reverse duplicate pattern embodyingthe present in vention; Fig. 2 is a plan view of the bottom face of thetop plate of such a pattern; Fi 3 is a transverse section on'the line3-3 of Fig. 1; Fig. 4 illustrates the service connection or switch'forthe pattern heating cir cuits; and Fig. 5 is av detail of an electricconnection.

In the accompanying drawing we have illustrated the pattern plate asdesigned particularly for use in forming and marking buttonhole fliesinasmuch as this part of the shoe is one requiring a substantial amountof marking indications, but it will be understood that the invention isapplicable generally to shoe patterns and is not limited to anyparticular form of pattern.

In the drawing, the superposed patter plates 1 and 2 are reverselyduplicate in outline, each outlining the outtonhole fly of a shoe. Theseplates are held in properly assembled relation by means of a metallicedging portion 3 extending about the peripheries ofthe plates andproviding in addition a metallic guiding edge for the knife massesnvention is concerned, the position of the perforations and theirrelativearrangement is entirely immaterial and will differ with themarking indication design. The perforations in the plates are designedto receive metallic eyelets 6 through which an electric wire 7 may belaced from the inner face of each plate, this Wire passing from theinner face to the outer face through one aperture then transversely ofthe plate and to the inner face thereof through the adjacent aperture;thence lengthwise of the plate and to the outer face thereof through thenext aperture and so on, as will be evident from Figs. 1 and 2 of thedrawing. The exposed indication marking portions of the wire areindicated at 8, Figs. 1. and 3. The terminals of the heating circuit forthe lower plate are indicated at 9, 10 and those for the upper plate areindicated at 11, 12 (Fig. 2). These terminals are preferably in the formof sockets to receive suitable service connections and are positioned atthe opposite face of the plate from their exposed marking portions.

The service terminal connection in'efi'ect a switch member andpreferably takes the form of a handle 13 having projecting from its baseservice wire terminal plugs 14 arranged for insertion throughperforations in opposite faces of the plates to connect with theterminal sockets 9. 10 and i1. 12. The service wires 15 and 16 lead fromthe service connection handle to suitable current connections. The bodyof the handle 13 is provided on one face with a cut-out portion 17disclosing a portion of wire 18 forming an indicator or tell-talesection. This exposed wire portion is preferal'ily of substan tially thesame heating capacity as the exposed marking portions 8 of the heatingcircuits so that the condition of the exposed indicator 18 is evidenceof the condition of the marking portions 8 of the heatingcircuit wireson the opposite face of the pattern plate.

\Vhcn the pattern is employed in a double one, as illustrated herein, asheet 19 of suitable insulating material such as asbestos is preferablyinterposed between the adjacent inner faces of the connected plates, asbest seen in Fig. 3 of the drawing.

It will be obvious that unless additional conductors are provided theportions of the wires 7 upon the inner faces of the plates will becomeheated. to the same degree that the exposed marking portions 8 areheated. To maintain the interior face of the heated plate in acomparatively cool state so that the plate may be handled by theoperatpr, metallic strips '20 are preferably formed integral with theeyelets (3 and are applied to the inner faces of the pattern plates sothat the current will pass through the portions of the conductor uponthe inner face of the plate and also through these wire strips 20,distributing the current so that it can not possibly heat the insideface of the plate to any great degree. To obviate the necessity ofproviding a long strip for the re turn portion of the conductor. thereturn portion of the wire may be made of a larger size. as indicated at21. Figs. 1 and 2.

It will be evident that in the use of a pattern plate. such as isdescribed, the service connection 13 is applied to the plate at the faceopposite that to be heated. its terminal plugs l-l fitting in theterminal sockets of the heating circuit of the pattern plate to beheated and its indicator 18 informing the operator of the heatedcondition of the marking wires of the pattern plate. The operator placesthe pattern upon the shoe material at the desired point, drawing hisknife around the edge to cut out the shoe part while at the same timethe heated marking portions of the wire are searing or cauterizing thesurface of the material upon which they rest. Inasmuch as the terminalsof the heating circuits are located at the faces of the plates oppositethe cautcrizing wires. only one may be heated at a time, and. as isobvious. this heated plate is the one which is being used for cuttingout the shoe part;

It will be understood that the structure and use of the invention asrecited herein is descriptive rather than definitive and that thestructure and application of the device may be variedwithin the scope ofthe claims and the'spirit of the invention. As an illustration. it is tobe noted that the device of the present invention is adapted also foruse in marking corresponding shoe parts which have been previously cutout from sheet material by an agency other than the pattern plate andoperatons knife. such. for instance. as shoe parts cut out by clickingmachine dies. 7
